UNITED STATES PATENT OEEICEo CHARLES J. GAUME, OF BROOKLYN, ASSIGNOR TO THE CONTINENTAL GAS ENGINE COMPANY, OF NEW'l YORK, N. Y.

GAS-ENGINE.

SPECIFICATION forming part of Letters Patent No. 302,478, dated July 22. 1884- Application tiled December 15, 1883. (Nolmodel.)

.To .all whom it may concern,.-

Be it known that I, CHARLES J. B. GAUME, of the city of Brooklyn, county of Kings, and State of New York, have inventeda new and useful Improvement in Gas-Engines, of which the following is a full, true, and exact descripy tion, reference being had to the accompanying drawings.

This invention relates to a method of cooling to a degree below'the normal temperature the gas to be exploded in gas-engines, whereby, the gas being less in volume when admitted to the engine than it otherwise would be, a more beneficial result is derived from its subsequent heating by the explosion.

My invention will be readily understood from the accompanying drawings, in which Figure l isan elevation of sufficient of a gasengine to illustrate Iny invention. Fig. 21s a detached sectional view.

Airepresents a gas-engine, preferably of the form patented to Ine 011 the 3d day of May,

' Other methods of connecting the cooler may be employed; but the one shown is simple and 3 5 efficacious.

I am aware that in gas-engines the inlet gaspassages have sometimes extended through parts of the cylinder inclosed by the waterjackets; but in such cases the action of the 4o jacket is merely to prevent ignition or overheating of the gas, whereas my invention consists in subjecting the gas to a temperature below that of the external air, and mue-l1 below that of the jacketed cylinder, whereby it is 45 not only cooled, but greatly condensed.

What I claim as my invention, and desire to secure by Letters Patent, is-

'1. The Inode of securing an increased charge for gas-engines, consisting in rst cooling the 5o gas below the normal temperature to reduce its volume and increase its density, and in introducing it while thus cooled and condensed into the explosion-chamber, substantially as described.

2. The combination of the cylinder, gas-inlet pipe, and water-jacket surrounding said pipe at a point beyond and free from contact with the cylinder, to prevent the convection of heat, as set forth.
